Measles

Last updated on Monday, 2 September 2024 at 01:59pm

Measles is a viral infectious disease. This page provides information about measles cases in England.

Cases are confirmed through either local or reference laboratory testing.

Numbers shown here are provisional and subject to change as:

  • more suspected cases undergo confirmatory testing
  • some locally tested cases are discarded after obtaining further epidemiological information or undergoing confirmatory testing at the reference laboratory

We update measles data every 2 weeks on a Thursday at 9.30am.

Since 1 January 2024, there have been 2,387 laboratory confirmed measles cases reported in England.

47% (1,121 of 2,387) of these cases have been in London, 23% (544 of 2,387) in the West Midlands, and 8% (182 of 2,387) in the East Midlands. The majority (1,473 of 2,387, 62%) of these cases were in children aged 10 years and under, and 31% (749 of 2,387) were in young people and adults aged 15 years and over.

In the 4 weeks since 29 July 2024, there have been 122 confirmed cases. Data reporting lags have had the greatest impact on the most recent 4 weeks and therefore the reported figures are likely to underestimate activity. London accounted for the highest proportion of these (73%, 89 of 122). 14% (17 of 122) of cases have been in the South East, and 8% (10 of 122) in the West Midlands.

There was a rapid increase in measles cases in late 2023 driven by a large outbreak in Birmingham. Activity in Birmingham has now decreased to lower levels. There has subsequently been a rise in cases in London and small clusters in other regions.
